module). Track 1 provides an output of 0.5 V with the pedal at rest and 2.0 V at 100% full throttle. Track 2 provides an output of 0.5 V with the pedal at
rest and 4.5 V at 100% full throttle. The signals from the two tracks are used by the ECM (engine control module) to determine fueling for engine
operation and also by the ECM (engine control module) and the TCM (transmission control module) to initiate a kickdown request for the automatic
transmission.
The ECM (engine control module) monitors the outputs from each of the potentiometer tracks and can determine the position, rate of change and
direction of movement of the throttle pedal. The 'closed throttle' position signal is used by the ECM (engine control module) to initiate idle speed control
and also overrun fuel cut-off.
